1. Why buy a 5.1-channel home theater?
The last time a poor family home theater program featured weekly home comforts - talking about how to build a poor home theater? As a result, valued friends pointed out: "You have no 5.1 audio, what home theater!" Upgrade 5.1 audio to enhance the viewing experience. In the article, I also mentioned that there are plans to upgrade, so I saw several sets of amplifiers and boxes, put it in the shopping cart, did not expect the event to come, so decisively took the opportunity to upgrade this 5.1 suit.
2. Why buy Tianlong X520BT&JBL Cinama510? Cheap!
The original price of 7680 (no one would buy it if it is not the event), when the red part is written in 3.14-3.16 day payment is only 3699 yuan, the key is the 14th morning there is no "this product can not use the East" this disappointing remarks. 
Decisively sent to the Aunt broke the news, the results have already valued friends broke the news, was rejected by the Xiao Bian, when the BUT was released can not use the East
In the morning, the handsome man had already used the 2000-200 large-scale electricity discount and added 12 white bars to interest-free. He used the Jingdong card exchanged by his aunt to reach 3299.
On the second day of the order, he was eating lunch and wondered how the weekend could experience a new sound. As a result, a Beijing telephone call, claiming to be Jingdong, said that the sale was too hot and the package was out of stock. It was on March 21st next Monday. I thought for the sake of not losing the 2000-200 embarrassment, I endure it. Order No. 19 Jingdong was delivered by Debon Logistics (JD's self-operated, factory delivery....)
Received a phone call, "Shunfeng" said there is my 2 express delivery guards, it is estimated that the file, hang up. . .
As a result, when the text message rang, Nima was the phone call of Debang and the display was "Shunfeng." It was a cell phone pit, so I got into the garage with my parcel. 
An AV amplifier and a set of 5.1 audio components are not heavy and they are too bulky.

After I finished the installation, I couldn’t wait to use it. Considering that there was no big picture, the movie didn’t reflect our audio system. I chose the Lord of the Rings, The Hunger Games and The Dragon Hunting to watch the movie.

music
After connecting with the mobile phone app Bluetooth, the official soundtrack of the "Guardian of the Galaxy" inside the mobile phone was still quite sensational.
Connect the power amplifier with the Bluetooth mobile phone app and play the music of the Galaxy Guard.
Experience summary
Tianlong X520BT&JBL Cinema510, as an entry-level price-performance 5.1 home theater, to me to meet the audiovisual needs of the average family, although the five 3-inch satellites seem petite, but several films in the surround sound performance can be circled It can be said that the central dialogue is also very clear. In combination with the 6-inch subwoofer, it shocks the Lord of the Rings in the Palano Plains warfare, the war scenes in the hunger game, and the explosions of the underground fortifications in the quest for dragons. Has a strong sense of presence. Compared to the original Philips sound bar, there is still a clear improvement. (Thank you for your sincere suggestions in the last value-for-money review.) At the same time, the size of the satellite box is very small, and it can be used with various decoration styles. It will not be too abrupt. The amplifier interface is also advancing with the times, supports 5 HDMI video source inputs, and supports HDCP2.2 to prepare for future 4K upgrades. In combination with DTS and Dolby Audio, it can provide users with a very good listening experience. But the fly in the ointment is that JBL's center speaker looks exactly the same as the surround. It feels weird, and the long, slightly long bar in the middle home is relatively normal, although it does not affect daily use.
